To all whom it 'may emmer/lf.'

Be it known that l', ABRAM Cox Mo'r'r, Jr., a Citizen of the United States, residing;` in Philadelphia, Pennsylvania, haveI invented certain Improvements in (jonilz-ined (las and Coal Heating-Stoves, ol' which the following' is a speeiiieation.

The object, ol my invention is to malte a heatil'ig stove .so that either uns or eoal can hc used as fuel. This olfijet't l attain. in thc l`ollowing manner, rrii'erenee heine' had to the aeeoinpanyinnY drawings, in which?" Figure l, is a vertieal sectional view ol' m v improved stove partly in elevation showing' the gas apparatus in position; Fig. 2, is :i vertioal seetionn-i view on the line2-`2, Fig. l, partly in elevation; Fig'. his a seetional view et' a portion of thestove arranged to hurn coal as the fuel; and Fig'. il, is a perspective view of the gas burner.

A is the body of the heating stove ol' the ordinaryv shape. 'lhis hodv is mounted on :t base (t provided with suitable legs f/f.

B is the ash pit.

C is the lire pot having' the i'ingers e in the present instance.

D is the grate having a central opening d and a slide D is mounted in ways so as to open or close said opening'. 'lhe slide is provided with a suitable handle d projecting through an opening n the hase of the stove.

E is a central chamber or hopper l'or eontaining the coal, when coal is used as the fuel.

of is the opening i'or the eseape ol' the prod nets of eoiuhustion.

At the hach ol thestove are tivo llues fr* and in the base isa lluo it and the products ol' combustion can oe either directed by the damper i; to the outlet fr directly l'roni the combustion ehanilier, or indirectly through the lines o3, n and then to the outlet. This is an Ordinar)v type ol' heating stove.

In nrany eases it is more convenient to use gas as a fuel rather' than eoal and especiallyr where the heat is not required at al times, such as in the l'all :md springr oi' the year. i have, therefore, designed a stove which van be used either lor las or coal, :is desieed.

The gas apparatus can he readily removed' Without dismantling' the stove so that it ezn: be shifted in a very l'ew minutes troni one style of heater to another.

At each side ol' the stove in the present instance are lenders b which are usually intended onliv l'or ornamental purposes, hut l utilize one olI these endet's to carryv the gas supply pipe l, which has a hranrh i provided with a valve z, and this liraueh enters an opening iu ille casting4 Vl seeured to the hase section oll the stove in line with the ash pit.

N is a gas hurner circular' in forni iu the present instance, and is provided with a su ply pipe n having a liraneh n turned at rigiit angles to the pipe n, so that when it is in position it is in line wit h the gas pipe 'i and its end is so shaped as to rest iu the casting l. 'l`he gras hurner N is deliielnthly mounted in the 'lire pot above the `grate, the legs restin;y` upon the grate and the supply pipe n extends through the central. opening d inthe Igrate, the slide l) having been moved to one sido as indicated in Fig. l, the hurnei' being mounted in the stove Without dismantling any portion ofv tln` grate or lire pot.

l preferablyr mount a cage M in the 'ire pot ahove the liurner to hold eornposit-ion blocks representing eoal; the hurning; gas will ass through the body ol' niaterial and heat 1t to inealnleseenee, making it appeal' as ilE coal was the l'uel. u

ln order to delleet the products of conihustion l preferably mount a shield K ahove the lire pot at the hack of the stove directly in front ol' the damper l, the lower end of the shield resting` on the lire pot and the upper end resting against the walls of the hopper E, so that while the damper b is open, as indicated in Fig'. 2, the products of coinhus tion will not )ass direetlv to theI tlue but will he delleeted y the shield.

When it is desired to place the gas burner in position the iire door e is 'lirst opened and the depending portioi of the hopper E is pushed up, the slide D is moved out and the )urner is passed through tho'lire door into the lire pot', and turned so that the pipe l1t will pass through the opening' in the grate, after which it is turned so that il will pass into thc casting l in direet line with the gas pipe. The cage )il is then placed in position and the dellector li is also placed in position, after which the hopper 4is lowered and the stove is-thcn ready to burn gas its a l'uel.

l claim:

'lho combination in a heatingr stove, oi n liodyA portion, having1 a lire pot. and ash pit, a n'l'ate with an opcn center separatingI the lire pot litoni thc ash pit, :i slid(` l'ot closing said opening, the side wall ol tht'l :ish pit hav- `glad pi e depending bbfly or the burner being supported by the P ing an opening therein, a gas ipe having an extension terminating at the opening, a de- 'tachable Circular burner having a right anflom its center, the

grate and the` pipe extending through the opening in the grate and :dining with the opening in the side Wallro the ashrpit.

.In testimony whereof, I have signedr my name to 'this s ecication, in the presence 10 of two subscribing Witnesses.
